Specifications Height: 150MM Width: 90MM Reusable Hanging Dehumidifier Pouches This handy little Hanging Dehumidifier bag will remove excess moisture in the air around it. Dehumidifying the air will prevent mould, condensation, damp and water damage, while making your house more inhospitable for dust mites. The benefit of having such a compact bag is that you can hang it up in small spaces such as: a car, wardrobe, suitcase, trunk and anywhere else you can think of. It’s designed to be effective in enclosed spaces so it will not dehumidify a large room. Please note, these bags cannot be refilled because they are reusable. Once the bag is completely full the penguin on the front will turn pink - from blue - indicating that you will need to microwave it for 3 to 8 minutes at a power level of 600W. Make sure to let the bag completely cool down and dry before reusing. Due to storage conditions, these may need drying out prior to first use.
